Zamak 3 vs. CC754S Brass

Zamak 3 belongs to the zinc alloys classification, while CC754S brass belongs to the copper alloys. They have a modest 37% of their average alloy composition in common, which, by itself, doesn't mean much. There are 29 material properties with values for both materials. Properties with values for just one material (7, in this case) are not shown.

For each property being compared, the top bar is Zamak 3 and the bottom bar is CC754S brass.
